mbrs130lt3g

If you’re looking for a diode that’s efficient with low voltage drop, the MBRS130LT3G from ON Semiconductor is a great pick. It’s a Schottky diode rated up to 30V and 1A, with a low forward voltage drop around 0.35V—much better efficiency compared to regular silicon diodes. Its minimal reverse leakage current makes it ideal for battery-powered or low-power applications. Packaged in an SMB SMD format for easy automatic assembly, it operates reliably from -65°C to +125°C. Perfect for DC-DC converters, reverse polarity protection, or high-frequency rectification and clamping circuits.

mbrs130lt3g pinout

The MBR130LT3G’s anode connects to the power input, and the cathode connects to the load output, allowing current to flow out of the load. The metal tab on the back acts as a heat sink, often connected to a large copper area on the board. Make sure the polarity is correct—anode to input and cathode to output, or the diode won’t work properly. Since it handles higher current, a good heat dissipation design is essential to prevent overheating. Also, ensure your circuit design doesn’t exceed the 40V reverse voltage and 1A current rating.

If you’re looking to replace the MBRS130LT3G, the SS14T3G and MBRS140T3G are good alternatives. Both offer the same current rating and 40V reverse voltage. SS14T3G has a smaller SMA package, ideal for tight spaces, while MBRS140T3G offers better heat dissipation for higher power designs. If you need more current, the 1N5822 supports 3A, but it comes in a larger package, making it better for higher power applications.

mbrs130lt3g smps rectifier circuit

In this bridge rectifier circuit, the AC input is adjusted by a transformer and then enters the rectifier. Four diodes are arranged in a bridge configuration, ensuring that the current always flows in one direction, converting it to DC. When the positive half-cycle of the AC reaches, two diodes conduct, and during the negative half-cycle, the other two conduct, ensuring the load gets steady DC. Using the MBRS130LT3G Schottky diode offers two main benefits: a low forward voltage drop (0.45V) reduces power loss and heat, and its fast recovery time ensures stable performance in high-frequency applications, improving conversion efficiency.

mbrs130lt3g reverse polarity protection

The MBRS130LT3G is typically used as a reverse polarity protection diode at the power input. When the power is connected correctly, the diode conducts forward, allowing current to flow to the load, with a forward voltage drop of just 0.45V. When the power is connected incorrectly, the diode is in reverse cutoff, blocking the current and preventing damage to the circuit. This makes it ideal for battery-powered systems, switching power supplies, and automotive circuits, protecting against damage from reversed power connections.

The MBRS130LT3G, with its low forward voltage drop, is perfect for high-efficiency power designs. In switching power supplies (like DC-DC converters and AC-DC adapters), it reduces energy loss and boosts efficiency, especially under high load and high-frequency conditions. In battery-powered devices, it helps extend battery life by minimizing power loss. It’s also used in reverse voltage protection circuits to prevent damage when the power is connected incorrectly. Plus, it works great in LED drivers and high-speed switching circuits, improving system efficiency and response times.

The MBRS130LT3G is a Schottky diode commonly used in power supply systems, especially in switching power supplies, DC-DC converters, and AC-DC adapters. Its low forward voltage drop (around 0.45V) helps reduce power loss and improve conversion efficiency, making it great for high-frequency and high-current loads. Its fast recovery time also makes it ideal for efficient power designs and extends battery life in low-power devices. In reverse voltage protection circuits, the MBRS130LT3G ensures the circuit won’t be damaged if the power is connected incorrectly.
